Edit

The textarea is replaced by an iframe ( in a textarea I don't think you can put image ).

This seems to be an answer about how to get content from cke iframe : Get CKEditor content? - jQuery

Try this it will alert something if you have anything in the textarea. Since it is an input element it will have value property so just use val() method.

$("#txt").val();

you have to use getData() to get the innerhtml from CKEditor

$('#txt).val(); works only for simple textarea. And you want to text CKEditor-textarea. See here stackoverflow.com/questions/4826036/get-ckeditor-content-jquery. Looks like your question is related to it.

to get inner text of textarea like .html() method you can use this code to replace \n with

$("#txt").val().replace('\n',"<br />");
